Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a flow path switching device for supplying fluid such as liquid or powder to multiple locations.
The flow path switching device of the present invention is effective for processes that require switching fluid flow paths to supply fluid to multiple locations, such as for reflux distribution in a distillation column.

[Conventional technology]

Conventionally, the method of switching the liquid flow path and supplying fluid to multiple locations involves branching a predetermined number of pipes, installing a valve in each branch pipe, and supplying liquid to a predetermined pipe by opening and closing each valve. Generally, a method is adopted in which the liquid flow path is switched using a switching device or the like.

[Problem that the invention attempts to solve]

However, in the conventional method of providing a branch pipe, for example, liquid remains in the branch pipe while it is closed, and the remaining liquid from the previous time is mixed in when it is used next time, so the liquid supplied immediately after switching has a different composition. There are problems such as changes. Further, in the conventional system using a switching pot, depending on the structure of the pot, the amount of residual liquid in the closed channel is relatively small, but there are problems such as the inability to increase the number of channels to be switched.

[Means for solving problems]

The present invention provides a main body in which a plurality of compartments are provided at the bottom, each having a discharge part at the bottom, and a rotatable container having a discharge pipe at the bottom is positioned above the compartments, and An introduction pipe is provided with the tip facing the container upward, and the fluid flowing in from the introduction pipe is received by the container, and by adjusting the rotational position of the container, the fluid is discharged from the discharge pipe of the container. The above problem is solved by providing a flow path switching device characterized in that the fluid is sent to any one of the plurality of compartments.

〔Example〕

Hereinafter, an embodiment of the flow path switching device of the present invention shown in the drawings will be described.

In the drawings, reference numeral 1 denotes a main body, at the bottom of which a plurality of partition plates 2 are arranged radially from the vertical central axis of the main body 1, and a plurality of compartments 3 are provided. Each compartment 3
has a structure with an upper opening, and a discharge pipe 4 is provided at the bottom as a discharge section to a predetermined location.

Further, 5 is a rotary shaft provided to be freely rotatable with respect to the main body 1 so as to coincide with the vertical central axis of the main body 1, and 6 is a compartment 3.
The container is rotatably provided in the main body 1 and located above the container, and the rotating shaft 5 is integrally fixed to the container 6 at the vertical central axis of the container 6. The container 6 has an open top structure, and a discharge pipe 7 is suspended from the bottom of the container 6 at a position other than the center. Further, the rotating shaft 5 is configured to stop at an arbitrary rotation angle, and at that time, the discharge pipe 7 of the container 6 faces a desired compartment 3.

Reference numeral 8 denotes an introduction tube, which is provided above the container 6 with its tip facing the opening of the container 6.

In addition, 9 is a lid of the main body 1, and 10 is a drive unit for the rotating shaft 5.

In the flow path switching device configured as described above,
Fluids such as liquids and powder particles flowing from the introduction pipe 8 are
It is received in the container 6, sent out from the discharge pipe 7 to the compartment 3 of the main body 1, and supplied to a predetermined location from the discharge pipe 4. At this time, the flow path is switched by adjusting the rotational position of the rotating shaft 5, and the fluid is supplied to any compartment 3. Furthermore, by providing the discharge pipe 4 at the lowest position of the compartment 3 as in the embodiment, when the supply of fluid from the discharge pipe 7 is stopped, the entire amount of fluid in the compartment 3 can be discharged and the compartment 3 can be drained.
It is possible to prevent any fluid from remaining inside.

[Effect of idea]

Since the flow path switching device of the present invention is configured as described above, it is possible to easily switch and supply fluid to any one of the plurality of compartments, without causing residual liquid in the closed flow path. , fluid can be supplied to multiple locations.
